Audio Note (UK) traces its roots to 1991, when Peter Qvortrup, a seasoned valve amplifier designer with prior experience at Audio Innovations, founded the company in Sussex, England. Collaborating initially with Hiroyasu Kondo, Qvortrup launched the OTO PP integrated amplifier that year—a modular valve design still in production today, hand-built in their Partridge Green factory. This enduring debut underscores the brand's commitment to timeless engineering over fleeting trends.
The company specializes in complete, in-house valve-based audio systems, crafting everything from turntable cartridges and tonearms to preamplifiers, power amplifiers, DACs, speakers, and cables. Their modular philosophy permeates the lineup, allowing tailored configurations while prioritizing premium components like custom-wound transformers and silver wiring for purest signal paths.
Positioned as Europe's largest and most prestigious maker of ultra-performance valve hi-fi, Audio Note (UK) commands the high-end niche, appealing to discerning audiophiles seeking musical authenticity over mass-market convenience. With a global distribution network and a reputation for longevity, it stands as a boutique benchmark for those investing in heirloom-grade sound reproduction.
